Thanks for posting that. It's a fun post to see.
Funny how expensive the small gauge shells are compared to the bigger and more used ones (in normal times). I wonder how many of the western folks far from civilization milled their own powder in those days, not for a lack of goods to trade for it, but for one of logistics. If you're carrying a gun every day doing your rounds or hunting, you don't shoot very many rounds, so my guess is that 5 pounds would probably last them at least a year.
